A Technician suffers a flash burn to the forearm while working on a breaker. The On-site nurse cleans wounds, gives cold packs and everyone heads back to work.
Does that go on the OSHA 300 log?
Nothing else sparks debate like that one question in plant offices. Report too little and you are looking at a citation. Report too much and your incident rate skyrockets for no good reason, your premiums rise, and your safety record doesn’t reflect reality.
Here’s the good news…
The rules aren’t grey at all like the arguments make them out to be. Once you learn the test, the majority of calls are only 2 mins.

Why Equipment Incidents End Up On The Log So Often
Medium voltage assets are playing a role in such a large percentage of recordable cases because the energy is stored waiting.
Racking a breaker. Pulling a draw-out unit. Opening a cubicle door for a thermal scan. Routine work. One loose connection, one old insulator can change that routine job into a burn, shock or blast injury in less than a second.
Equipment design plays a huge role in this equation. A modular switchgear lineup that divides functionality into separate, compartmentalized sections restricts the distance an event can spread. Enclosed designs restrict the exposure even more: gas-insulated switchgear contains the live bus within a sealed enclosure, meaning your technicians aren’t working near open conductors as much when performing routine inspections or maintenance. When you have less exposure points throughout your modular switchgear lineup, you have less chance of arc flash incidents, and less chance of arc flashes means less log entries.
Here’s the proof. Between 2023 and 2024, there were 5,180 electrical injuries resulting in days away from work — an increase of 59% from the prior two years.
That’s the wrong direction.
The Three Questions That Decide Every Case
Scratch everything you heard in the kitchen. A hurt only goes on the log if YES is the answer to all three of these.
1. Is it work-related?
It is work related if something that happened or you were exposed to at work caused, aggravated or contributed to the injury. Tech sustains burn injury while testing relays. YES! Tech strains knee while stepping off a ladder in the switch room. YES!
Excuses. There are few. Food-truck injuries. The sniffles. They’re narrow. Don’t broaden them.
2. Is it a new case?
An old injury that is freshly sustained is always considered a new case. Likewise, an old injury that has healed but is re-aggravated by a new work event is also a new case. However, if treatment is ongoing for the same injury (e.g. an arc flash burn received in March), then a September check-up is not a duplicate case.
3. Does it meet one of the recording criteria?
This is where the decision actually gets made.
The Six Recording Criteria
According to OSHA’s general recording criteria, if a work-related injury leads to any one of the following, it is recorded on the log:
- Days away from work — even one calendar day
- Restricted work or transfer to another job
- Medical treatment beyond first aid
- Loss of consciousness
- A serious injury or illness that’s been diagnosed by a doctor – A broken bone, a ruptured eardrum, or diagnosed medical condition
The criteria are independent of each other. An injury need not meet two, or three. Just one will suffice.
That catches a lot of supervisors off guard. Someone who blacks out following a shock event and walks away with no treatment whatsoever is still considered recordable, just based on loss of consciousness alone.
First Aid vs Medical Treatment: Where Most Mistakes Happen
Here’s the part that matters most in day-to-day calls…
OSHA has a finite list for the definition of first aid. If it’s on the list it is first aid and you don’t record the case on that account. If it isn’t on the list it’s considered medical treatment and you put the case on the log.
Treatments OSHA counts as first aid include:
- Non-prescription medication at non-prescription strength
- Cleaning, flushing or soaking surface wounds
- Bandages, gauze pads and butterfly strips
- Hot or cold therapy
- Non-rigid supports like elastic bandages
- Tetanus immunisations
Ok now for the curveball: who is administering the treatment doesn’t matter whatsoever. A doctor putting a cold pack on is still considered first aid. A first responder suturing a laceration is still doing medical treatment.
Treatments that push a case onto the log include:
- Prescription medication — even a single dose
- Stitches, staples or surgical glue
- Rigid splints or casts
- Physical therapy
- Removal of foreign material from the eye with anything other than irrigation
Alright back to this flash burn scenario. Ice pack and a bandage? Nope. Recordable. Prescription burn cream? Yep. Recordable.
The Grey Areas That Cause Fights
A visit alone doesn’t count. Sending an operator to observe or do diagnostic work in a clinic — X-rays, blood tests, scans — is NOT medical treatment. If you did not receive treatment, do not count the visit.
Restriction work is a low standard. If the doctor indicates no ladder climbing for one shift, or if the injured party cannot do a routine task associated with their position, then it is restricted and should be recorded.
Noise induced hearing loss counts too! Switchrooms are loud work environments. A typical threshold shift that also results in a worker being at 25 decibels or more above audiometric zero is recordable, even if no blood was drawn.
To give you an idea of scale: there were 2.5 million recordable cases reported by employers in private industry in 2024. And OSHA compiled its new dataset from 370,000 Form 300A summaries. These injury and illness calls happen hundreds of thousands of times every year. Consistency is what separates a clean audit from a painful one.
Getting The Paperwork Right
A recordable incident requires a Form 301 Incident report and an entry on the Form 300 log NO LATER than seven calendar days after you become aware of the incident. Annual summary reports are posted on Form 300A between 1 February and 30 April. Records must be retained for five years.
Severe events don’t have months to report, they have hours. A fatality will need to be reported to OSHA within eight hours. Amputations, loss of an eye, or inpatient hospitalizations must be reported within 24 hours.
Those deadlines don’t pause while a committee debates the call.
Tying The Whole Thing Together
Recordkeeping isn’t the goal. It’s the scoreboard.
Of course, the best savings come from having fewer incidents to debate in the first place, which begins with the gear itself. Arc-resistant construction, remote racking, proper compartmentalisation throughout a modular switchgear portfolio, and a maintenance plan that is adhered to will benefit the numbers more than any meticulously completed paperwork can.
To quickly recap the decision:
- Work-related? New case? Meets a criterion?
- Check the treatment against OSHA’s fixed first aid list
- Remember that one criterion is enough on its own
- Log it within seven days, report severe events within eight or 24 hours
Document the process, train your investigators, and any given incident will be coded identically each time — regardless of the shift.
